Title:
トナー用結着樹脂の製造方法
Document Type and Number:
Japanese Patent JP4414284
Kind Code:
B2
Abstract:
The present invention relates to a process for preparing a resin binder for toner, comprising the steps of (A) carrying out an addition polymerization reaction of addition polymerization resin monomers including styrene in the presence or absence of an organic solvent; and (B) mixing the resulting reaction mixture from the step (A) with water at a rate of 0.002 to 0.5 parts by weight based on 100 parts by weight of the addition polymerization resin monomers per minute at a temperature of 100° to 300° C. during and/or after the step (A), wherein the amount of water to be mixed in the step (B) is 0.1 to 50 parts by weight based on 100 parts by weight of the addition polymerization resin monomers. The resin binder for a toner obtained according to the present invention can be used, for instance, for developing electrostatic latent images formed in electrophotography, electrostatic recording method, electrostatic printing method, and the like, and a toner containing the resin binder.
